Can anyone help me with ideas for a funny saying or something different or cute for the tee shirts and caps I am making up for 20 people.

Thank you if you can think of something.

I saw these on a senior site:

1. Don't worry about avoiding temptation. As you get older, it will avoid you.
2. The older I get, the better I was.
3. My wild oats have turned to shreaded wheat!
4. Young at heart. Slightly older in other places.
5. I'm Not over the hill, I simply can't climb it.

Are we there yet?
Don't mess with me, I got nothing to lose.
Seen it, done it, and lived it. Buzz off.
Can't see, can't hear, but can nag.
Watch out, I am on Viagra.
I don't need no stinking grandchildren!
